1. How To Reheat Frozen Mussels

If you have frozen mussels stored in the freezer for up to 3 months, you need direction on how to thaw and reheat them. Although mussels can stay fresh in cool temperatures for a long time, they need the wrong reheating technique to become bad. 

“Can you heat frozen mussels?” The answer is yes. 

But how to prepare frozen mussels? Just follow my below instructions:

  1. Remove the mussels from the freezer and let them sit in a bowl at room temperature for the natural thaw. After 10-15 minutes, when the ice has melted into water, remove the water and let the mussels sit dry.
  2. If your mussels still have shells on, you need to remove them by throwing mussels into a large saucepan and steaming them for 5-7 minutes. Make sure to boil about 200 ml water together to make the shell-opening process faster and more effective.  If you have white wine, pour in some drops to make the newly-opened mussels absorb the wine to eliminate the ocean smell. When you see all the shells have opened up, turn off the stove and discard the leftover water.
  3. There might be some mussels with beards on once you open them. Remove them with a knife and cleanse all mussels with water again to remove all dirt and debris.
  4. After 5-7 minutes of steaming, your mussels are cooked now, but you need extra cooking time for seasoning. Place your mussels in a bowl with water and seasoning species, and heat it in 2-3 minutes for the seasoning to absorb in your mussels. 

2. How To Reheat Cooked Mussels on the Stovetop

Step by steps instructions:

  1. For unopened shells or cooked mussels with shells on, you should remove all shells before reheating. If you want to keep the shells for garnish, later on, feel free to keep them. After finishing reheating the mussels, you can put the mussels on the shells for garnish. 
  2. For cooked mussels stored in the fridge, their meat tends to be tough and bland, so the reheating process must help the mussels to be flavorful and chewy again. After removing all the shells, heat a pan with high heat oil and toss all mussels in. 
  3. Season mussels with butter, rosemary, garlic, salt, and pepper and cook them for 3 minutes under high heat for the spices to absorb ineffectively. When you see their flesh becomes tough, remove them immediately; otherwise, you will overcook and burn them. 
  4. Let the mussels sit at room temperature for a few minutes before serving them on plates. That’s how you can reheat mussels on the stovetop.

3. How To Reheat Mussels in Broth

Unlike other seafood, which is delicious when served alone, mussels are best to taste broth dishes. If you go to an Asian seafood restaurant, you will notice a mussel recipe that includes broth as the flavorful water will make you experience mussels most finely. 

In case when you have a leftover mussels broth, let’s see the best way to reheat mussels with broth:

  1. Take the leftover broth out of the fridge and separate mussels from the broth. Remove any shell remaining for an efficient reheating process. 
  2. Reheat mussels in the oven or on the saucepan for a few minutes to cook to hot heat. With these methods, you can season mussels with additional spices to make them more flavorful. If you think that you don’t need more seasonings for your mussels, you can toss them in a steaming pot with water and white wine.
  3. For the broth, especially fish stock or fish stock substitute, you can toss it in a microwave-safe bowl and heat it for 1-2 minutes if you are in a hurry. If you are more careful, let the broth sit in a saucepan and boil it traditionally until it is hot for how to cook pre cooked mussels
  4. At the last 30 seconds before you bring out the broth from heat, toss in the mussels to have a combination of both ingredients cooked together. Do not let the mussels sit for too long, or you will overcook it. This last-minute add-in will ensure your dishes maintain all of the original flavors and are ready to be served.

How To Tell If Mussels Have Gone Bad? 

For those of you who don’t store mussels properly, they may have gone bad without you knowing anything about it. How to tell if mussels have gone bad so that you won’t accidentally eat them and end up having digestive disorders? 

Here are the signs to check among your leftover mussels:

  • If you have any mussel that you cannot open or have a hard time opening, it can be a dead or an unhealthy one that you should discard. 
  • Detect any mussel with broken shells? Then the mussels may have been spoiled as well. 
  • In case you can detect odd smells, other than the natural ocean odor or seasoning smell, then the mussels may have gone bad as well. Spoiled mussels will have a bad pungent smell resembling the smell on how to tell if tilapia is bad. If you suspect a weird smell from seafood, it’s best to throw them away for you and your family’s food safety. 
  • If you see any mussels with an odd color, such as being too dark or changing into a whole different color, you should throw them away.

After reviewing your mussels under these four criteria, they are safe to cook and eat if your mussels have none of these criteria above. 

How To Store Leftover Mussels? 

Storing leftover mussels is not easy to handle as seafood’s characteristics are much more complicated than meat. So, what is the best way on how to store cooked mussels so they won’t easily go bad in the fridge?


  1. If you intend to store a leftover mussels recipe with broth, separate the broth and the mussels into two boxes. Keeping these two together will make mussels go soggy. However, the broth helps retain the seasoning when you reheat mussels afterward, so make sure to keep it. 
  2. Whereas you are storing frozen or cooked mussels, make sure to use an airtight container and toss them all in. Don’t just use a simple box with a lid on it since the mussels’ environmental factors can make mussels go bad easily. 
  3. If you can remove all shells from the beginning, you should do it. It’s not good to store both mussel shells and flesh in the same box.
  4. How long do cooked mussels last in the fridge? They can last for up to 1 month under proper storage conditions. 


How long can mussels sit out?

In case you ask how long are mussels good for, the answer is mussels can only sit out at room temperature for less than two hours. After two hours, environmental bacteria will grow and attack mussels, making them go bad without you knowing it. It’s best to discard those mussels if you have left them at room temperature for too long. 

Can you eat cold mussels?

It’s best to cook mussels and serve them at a hot temperature. Cold mussels are not safe to eat as they may contain dirt and debris from the ocean, which can cause you disease if you accidentally swallow.
